C#Stopwatch的使用,性能测试

 

一,先开启开始或继续测量某个时间间隔的运行时间,然后停止,最后重置时间,输出.

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class TestPerformance : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        /*Var 性能测试 */
        Stopwatch stw = new Stopwatch();

        List<long> intlist = new List<long>();
        stw.Start();
        for (long i = 0; i < 10000000; i++)
        {
            var index = i;//使用var转入和转出
            intlist.Add(index);
        }
        stw.Stop();
        Label1.Text= stw.Elapsed.Ticks.ToString(); 
        stw.Reset();

        /*Int 性能测试 */



        List<long> intlist2 = new List<long>();
        stw.Start();//开始时间
        for (long i = 0; i < 1000000; i++)
        {
            long index = i;//使用int转入和转出
            intlist2.Add(index);
        }
        stw.Stop();
        Label2.Text = stw.Elapsed.Ticks.ToString();
        stw.Reset();


        /*Object性能测试 */
        stw.Start();//开始时间

        List<long> intlist3 = new List<long>();
        for (long i = 0; i < 1000000; i++)
        {
            object index = i;//使用object转入和转出
            intlist3.Add((long)index);
        }
        stw.Stop();
        Label3.Text = stw.Elapsed.Ticks.ToString(); 
    }
}

二,前端显示

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="TestPerformance.aspx.cs" Inherits="TestPerformance" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        Var:<asp:Label ID="Label1" runat="server" Text="Var"></asp:Label><br/>
        Int:<asp:Label ID="Label2" runat="server" Text="Int"></asp:Label><br/>
        Object:<asp:Label ID="Label3" runat="server" Text="Object"></asp:Label>
    </div>
    </form>
</body>
</html>

三,显示结果
